Wake-on-LAN

Simplified method (one host)

To use Wake-on-LAN with your server you must define some options such as the server's MAC address and (optionally) IP address. Use /etc/kvmd/override.yaml. The format is:

kvmd:
    wol:
        mac: ff:ff:ff:ff:ff:ff

Replace ff:ff:ff:ff:ff:ff with the MAC of your server. By default, a packet is sent via a broadcast request to the entire IPv4 network (255.255.255.255, port 9), but you can address it to a specific static address:

kvmd:
    wol:
        mac: ff:ff:ff:ff:ff:ff
        ip: 192.168.0.100
        # port: 9  # By default

... then restart kvmd using systemctl restart kvmd. It will now show up in the system button in the upper right corner.

GPIO method (multiple hosts)

Follow the manual for building the GPIO menu and use the wol driver to build a menu with many buttons tied to different hosts.
